THIN FIBER SCINTILLATION COUNTER FOR DETERMINING PARTICLE BEAM DISTRIBUTIONS IN ACCELERATORS
Thin fiber scintillation counters for studying particle beams in accelerators were developed using small plastic scintillation fibers made for use in high-energy physics. A fiber of 0.5-mm diameter or less and 1 to 10 cm long is mounted on a long thin (0.5-mm diameter and 20 ft long) two-layer glass pipe; the pipe serves as a light transmitter. The pipe passes through a vacuum seal and is joined to the face of a photomultiplier. Since the pipe is susceptible to radiation damage. it is placed inside a steel tube filled with Woods metal. Using this counter, electrons were shown to be trapped in the Astron E-layer tank for times longer than 1 sec, and estimates of the number of the initially trapped particles were made. (D.L.C.)
